I have looked through the pre-wired combiner section, and my best fit would be for a MNPV2-MC4-LV with 15A MNEPVs and a SPD. If the 2 wouldn't fit the SPD, I would go with a 3, but don't see that option either.
I currently have 1 string of 3 panels with Isc of 8.87 and maximum series fuse rating of 15A. In the future I could see another string of 3 happening, but even today with the single string I would like the breaker for disconnect. These are pole mounted, not building.
I can wire it myself of course, but thought I would ask as I see pre-wired items close to what I am thinking, (MNPV2 with fuses, and MNPV4 with breakers) just not exact. :)
